CMAKE - How to properly copy static library's header file into /usr/include?

Question

I\'m getting into CMAKE usage with C and actually I\'m creating two very small static libraries.

My goal is:

1. The libraries are compiled and linked into

Answer 1

In addition to the accepted answer, if you are creating a lot of libraries and the set_property syntax throws you off. You could wrap it in a very simple macro, such as:

# File: target_public_headers.cmake
macro(target_public_headers TARGET)
  set_target_properties(${TARGET} PROPERTIES PUBLIC_HEADER "${ARGN}")
endmacro()

Then you can use it like:

project(myproject)

include(target_public_headers)

add_library(mylib some.c another.c)
target_public_headers(mylib some.h another.h) # <<<<<

# If you're exporting this library then you need to tell
# CMake how to include the "installed" version of the headers.
target_include_directories(mylib
  PUBLIC $
  PUBLIC $
)

INSTALL(TARGETS mylib 
        LIBRARY DESTINATION some/libpath
        PUBLIC_HEADER DESTINATION some/includepath
)
