CMAKE : How to put absolute path in include directories

First, I am sorry if the question has been answered but I couldn't find any solution.

I am trying to compile a simple program with cmake. But I can't seem to include absolute paths.

My project (located in C:/path/to/my/project for the understanding) is simple with an include directory with header files. However, I must include another directory completely somewhere else.

My include_directories looks like this:

include_directories("${CMAKE_CURRENT_SOURCE_DIR}/include" "C:/path/to/my/other/directory/include")

However when I do :

get_property(dirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY INCLUDE_DIRECTORIES)
foreach(dir ${dirs})
  message(STATUS "dir='${dir}'")
endforeach()

To check my include directories I have the following answer:

-- dir='/c/path/to/my/project/include'
-- dir='/c/path/to/my/project/C:/path/to/my/other/directory/include'

So cmake interprets the paths as relative to my project folder. How can I force cmake to interpret them as absolute ?

I am using cmake v3.17.3.

EDIT

I have tried doing so but it doesn't seem to work either since the path is not appended to the INCLUDE_DIRECTORIES property of my target.

add_executable(app src1.c src2.c)
target_include_directories(app BEFORE PRIVATE "C:/path/to/my/other/directory/include")

Thank you by advance.

You can also write the path as:

add_executable(app src1.c src2.c)
target_include_directories(app BEFORE PRIVATE "C:\\path\\to\\my\\other\\directory\\include")

So after some research the answer is :

add_executable(app src1.c src2.c)
target_include_directories(app BEFORE PRIVATE "/C/path/to/my/other/directory/include")

The path I was referring to was wrong since I am on msys. Therefore c:/ should become /c/.
