Cmake : include directory - parent directory [duplicate]

Question

myproject/
  lib/
  src/
  project2/
    **CMakeLists.txt**
    test.cpp

I wrote CMakeLists.txt for compile 'test.cpp' file. I'd like to include /src because i should access src's file.

How could i include src file above? I tried like set(MORE_INCLUDE_DIR "-I${CMAKE_SOURCE_DIR}../../ but it's not working.

I should compile 'test.cpp' seperately please somebody help me.

Thanks in advance!

Answer 1

In this case, cmake required absolute path not relative. Let's try call include_directories like this:

    get_filename_component(PARENT_DIR ../ ABSOLUTE)
    include_directories(${PARENT_DIR}/src)

It can help.
