If I drop myprojJNI from the list of targets in the install(TARGETS, then error occurs (below ) indicating that dependendee target myprojlibShared needs its dependency myprojJNI because they are linked by  
target\_link\_libraries(myprojlibShared  
…myprojJNI …)  
install(TARGETS myprojlibShared myprojJNI … #need myprojJNI bc it was linked  
EXPORT myExportTargets …  
)

ERROR: CMake Error: install(EXPORT “myExportTargets” …) includes target “myprojlibShared” which requires target “myprojJNI” that is not in any export set.

In regards to JNI not found (smaller problem), it got fixed after adding

```auto
set(CMAKE_FIND_ROOT_PATH "${JAVA_HOME}")
set(CMAKE_FIND_USE_CMAKE_SYSTEM_PATH "${JAVA_HOME}")

```

before find\_package(JNI)

The problem was caused by find\_package(JNI) search path considering only /opt/xxxx and /opt/toolchains while jni.h is located at /opt/jdk/jdk8/include/jni.h. Debugging was done with set(CMAKE\_FIND\_DEBUG\_MODE TRUE) enabling printout of /opt/cmake/share/cmake-3.17/Modules/FindJNI.cmake:341 looking for jni.h find\_path considered the following locations list
