I'm on OSX and have the following CMakeLists.txt file:
cmake_minimum_required (VERSION 3.12)
project (Test)
add_executable (test main.cpp)
install (TARGETS test DESTINATION bin)
target_include_directories (test PRIVATE Source)
I get the error:
CMake Error at CMakeLists.txt:5 (add_executable): main.cpp not found
when running the makefile from the directory above Source.
I'm new to CMake so I've likely just made a noob mistake but I can't fix the error on my own.
If you want to add just Source/main.cpp then use
add_executable (test Source/main.cpp)
The target_include_directories or include_directories (that is for legacy versions of CMake) are telling to CMake where the .h files are.
target_include_directories is only going to add directories where your build system should search for include files, not source.
You can use add_subdirectory to add directories where source files live.
See documentation on target_include_directories and add_subdirectory.
