I am packaging myself module by cmake.
My CMakeLists.txt is:
```auto
install( TARGETS pA pB
EXPORT SustaoBasic
RUNTIME DESTINATION bin
LIBRARY DESTINATION lib
ARCHIVE DESTINATION lib
)
install(DIRECTORY package/ DESTINATION include
FILES_MATCHING PATTERN "*.h"
)
install(EXPORT SustaoBasic
FILE SustaoBasic.cmake
NAMESPACE SustaoBasic::
DESTINATION lib/cmake
)
include(CMakePackageConfigHelpers)
write_basic_package_version_file(
SustaoBasicConfigVersion.cmake
VERSION V1.0
COMPATIBILITY AnyNewerVersion # 表示该函数库向下兼容
)
configure_package_config_file(
SustaoBasicConfig.cmake.in ${PROJECT_BINARY_DIR}/SustaoBasicConfig.cmake
INSTALL_DESTINATION lib/cmake
)
install(FILES "${PROJECT_BINARY_DIR}/SustaoBasicConfig.cmake"
"${PROJECT_BINARY_DIR}/SustaoBasicConfigVersion.cmake"
DESTINATION lib/cmake)
```
Then, I can package it in installation path.
In additional project, the `find_package(SustaoBasic)` is OK.
When I `#include "pA.h"`, vs reports bug:
```auto
“pA.h”: No such file or directory
```
But, I am sure `pA.h` is included in `install\include`, and my `install\include` is:
```auto
install
include
pA
pA.h
pB
pB.h
```
Then, I want to find solution from `ITK` project. I find `ITK` generates a `ITK_INCLUDED_DIRS` variable. How can I generate the similar variable in my project?
Any suggestion is appreciated~~~

This is historical. There is no need for such a variable anymore. Instead, `target_include_directories(pA PUBLIC "$")` is probably what you want.

Thank you for you kindly suggestion.
But I feel some confuzed about how to use `target_include_directories(pA PUBLIC "$")`.
In following description, `packagePro` is the project I need to generate package. 'packageTest`is the project where I want to use`packagePro` package.
I have tried two experiments:
1. I add `target_include_directories(pA PUBLIC "$")` in the CMakeLists.txt of `packagePro`, which is:
```auto
...
install(DIRECTORY package/ DESTINATION include
FILES_MATCHING PATTERN "*.h"
)
install(EXPORT SustaoBasic
FILE SustaoBasic.cmake
NAMESPACE SustaoBasic::
DESTINATION lib/cmake
)
include(CMakePackageConfigHelpers)
write_basic_package_version_file(
SustaoBasicConfigVersion.cmake
VERSION V1.0
COMPATIBILITY AnyNewerVersion # 表示该函数库向下兼容
)
configure_package_config_file(
SustaoBasicConfig.cmake.in ${PROJECT_BINARY_DIR}/SustaoBasicConfig.cmake
INSTALL_DESTINATION lib/cmake
)
install(FILES "${PROJECT_BINARY_DIR}/SustaoBasicConfig.cmake"
"${PROJECT_BINARY_DIR}/SustaoBasicConfigVersion.cmake"
DESTINATION lib/cmake)
# add -------------------------------------------------------------------------------------
target_include_directories(pA PUBLIC "$")
```
The CMakeLists.txt of `packageTest` is:
```auto
project(PackageTest)
find_package(SustaoBasic)
add_executable(PackageTest main.cpp)
```
After building, the vs still reports `“pA.h”: No such file or directory`.
1. I add `target_include_directories(pA PUBLIC "$")` in the CMakeLists.txt of `packageTest`:
```auto
project(PackageTest)
find_package(SustaoBasic)
add_executable(PackageTest main.cpp)
target_include_directories(PackageTest PUBLIC "$")
```
But, it still report `“pA.h”: No such file or directory`.
Where should I add `target_include_directories(pA PUBLIC "$")`?
In addition, what path is `INSTALL_INTERFACE`? Is the `SustaoBasic_DIR` set in CMake?

You need to link to the `pA` target.

@ben.boeckel Thank you for you kindly reply, and I finally solve my problem.
The solution is:
1. add `target_include_directories(PackageTest PUBLIC "$")` in CMakeLists.txt of `packagePro`.
2. link to `pA` target in CMakeLists.txt of `packageTest`:
```auto
project(PackageTest)
find_package(SustaoBasic)
add_executable(PackageTest main.cpp)
target_link_libraries(PackageTest SustaoBasic::pA)
```

@ben.boeckel
`target_include_directories(pA PUBLIC "$")` can solve current problem.
The include folder is:
```auto
Package
pA
pB
```
Is it possible to include `Package` directory when `find_package()` or `target_link_libraries(PackageTest SustaoBasic)`?
Currently, I must `target_link_libraries(PackageTest SustaoBasic::pA)` to specify the `pA`. Can I link all libraries, just link `target_link_libraries(Pro ${ITK_LIBRARIES})`?

I find it better to link to the targets directly rather than through some variable. Fewer moving parts.
