Including glib.h in a CMake project

Trying to compile a library in Ubuntu with CMake and one of the file includes glib.h. The package is installed and glib.h is in /usr/include/glib-2.0/glib.h.

I added the following but compiler still cannot find glib.h.

FIND_PACKAGE(glib-2.0)
IF (glib-2.0_FOUND)
    INCLUDE_DIRECTORIES(${glib-2.0_INCLUDE_DIR})
ENDIF()

Anyone know what package I are suppose to look for?

Actual code that I ended up using is 

find_package(PkgConfig REQUIRED)
pkg_check_modules(GLIB_PKG glib-2.0)

if (GLIB_PKG_FOUND)
    message(Found glib-2.0)
include_directories(${GLIB_PKG_INCLUDE_DIRS})
Solution

  • I suggest you go through the link: How package finding works.

    As a reference, you can have a look at this CMake Module for finding glib2.

    The line of your interest here is:

    find_path(GLIB_INCLUDE_DIR NAMES glib.h PATH_SUFFIXES glib-2.0)

    I suggest you copy this module in your <project root>/cmake/ directory. And, then use a find_package in your root CMakeLists.txt file.
