CMake includes the path

Question

In a C ++ project, I would like to include header files as descendants of the project’s source directory without using UNIX directory shortcuts. or ... I'm not sure how to configure cmake to work with this.

I have a directory structure:

Root |-include | |- foo.h |-src | | foo.cpp 

Answer 1

put in root \ CMakeList.txt:

 project(root) include_directories(${root_SOURCE_DIR}/include) ... 

you can use root_SOURCE_DIR everywhere in subprojects.

Answer 2

Use include_directories( include ) for CMakeLists.txt in the Root folder. Or include_directories( ${CMAKE_SOURCE_DIR}/include ) from any subfolder.
