Hello,  
I am trying to write a CMake file for my project, this is the project tree :

```auto
Project
 I CMakeLists.txt
 I___src
 I-----I__main.cpp
 I-----I__window.cpp
 I-----I__windows.hpp
 I-----I__operations.cpp
 I-----I__CMakeLists.txt
 I
 I___incld
 I-----I__tinyexpr.c
 I-----I__tinyexpr.h

```

So now i am ge want to link the `tinyexpr.h` to the program, with g++ i know how to to it but with CMake it’s myFirst time,  
This is the CMakeLists.txt of project:

```auto
cmake_minimum_required(VERSION 3.20) 
project(MCalc) 
set(CMAKE_CXX_STANDARD 20)
 find_package(PkgConfig) pkg_check_modules(gtkmm gtkmm-4.0)
 add_subdirectory(src incld)

```

And this is the CMakeLists.txt of the src directory:  
link\_directories(${GTKMM\_LIBRARY\_DIRS} ${INCLD}) find\_package(PkgConfig REQUIRED) pkg\_check\_modules(gtkmm REQUIRED IMPORTED\_TARGET gtkmm-4.0 glibmm-2.68) set(SOURCES main.cpp operations.cpp window.cpp ${INCLD/tinyexpr.h}) add\_executable(MCalc ${SOURCES}) target\_link\_libraries(MCalc PkgConfig::gtkmm)

So if any one could help to make this CMakeFiles work with my program i would be really happy.
