CMake Package
The example shown below will work for INSTALLED projects only. I just hacked it out in a couple minutes, and it is not well tested. It should get you started, though. After installation, this "CME" sample project can be used by another project like this:
FIND_PACKAGE(CME) IF(CME_FOUND)
INCLUDE(${CME_USE_FILE})
# ... Use library ...
ENDIF(CME_FOUND)

- -----------------------------------------------------------------------------
- CMEConfig.cmake - CME CMake configuration file for external projects.
- This file is configured by CME and used by the UseCME.cmake module
- to load CME's settings for an external project.
- The CME include file directories.
SET(CME_INCLUDE_DIRS "@CMAKE_INSTALL_PREFIX@/include")
- The CME library directories.
SET(CME_LIBRARY_DIRS "@CMAKE_INSTALL_PREFIX@/lib")
- The CME version number.
SET(CME_VERSION_MAJOR "@CME_VERSION_MAJOR@") SET(CME_VERSION_MINOR "@CME_VERSION_MINOR@")
- The location of the UseCME.cmake file.
SET(CME_USE_FILE "@CMAKE_INSTALL_PREFIX@/lib/cme/UseCME.cmake")
- The build settings file.
SET(CME_BUILD_SETTINGS_FILE
"@CMAKE_INSTALL_PREFIX@/lib/cme/CMEBuildSettings.cmake")
- The CME library dependencies. These can be blocked by projects
- not interested in linking to CME's library.
IF(NOT CME_NO_LIBRARY_DEPENDS)
INCLUDE("@CMAKE_INSTALL_PREFIX@/lib/cme/CMELibraryDepends.cmake")
ENDIF(NOT CME_NO_LIBRARY_DEPENDS)
- Additional project-specific configuration settings can be set here.
- -----------------------------------------------------------------------------
- CMakeLists.txt
- Example project "CMake Export".
PROJECT(CME)
- Every project should have a version number.
SET(CME_VERSION_MAJOR 1) SET(CME_VERSION_MINOR 0)
- Example library.
ADD_LIBRARY(cme cme.cxx)
- Link to libm on unix for sqrt(). This is to demonstrate library
- dependency chaining.
IF(UNIX)
TARGET_LINK_LIBRARIES(cme m)
ENDIF(UNIX)
- Create the CMEConfig.cmake file for installation.
CONFIGURE_FILE(${CME_SOURCE_DIR}/CMEConfig.cmake.in
${CME_BINARY_DIR}/CMEConfig.cmake @ONLY IMMEIDATE)
- Save the compiler settings and library dependencies so another
- project can import them.
INCLUDE(${CMAKE_ROOT}/Modules/CMakeExportBuildSettings.cmake) CMAKE_EXPORT_BUILD_SETTINGS(${CME_BINARY_DIR}/CMEBuildSettings.cmake) EXPORT_LIBRARY_DEPENDENCIES(${CME_BINARY_DIR}/CMELibraryDepends.cmake)
- Install targets. Make sure the paths configured into
- CMEConfig.cmake match.

- -----------------------------------------------------------------------------
- UseCME.cmake
- This module is provided as CME_USE_FILE by CMEConfig.cmake. It can
- be INCLUDEd in a project to load the needed compiler and linker
- settings to use CME.
- Load the compiler settings used for CME.
IF(CME_BUILD_SETTINGS_FILE)
INCLUDE(${CMAKE_ROOT}/Modules/CMakeImportBuildSettings.cmake)
CMAKE_IMPORT_BUILD_SETTINGS(${CME_BUILD_SETTINGS_FILE})
ENDIF(CME_BUILD_SETTINGS_FILE)
- Add include directories needed to use CME.
INCLUDE_DIRECTORIES(${CME_INCLUDE_DIRS})
- Add link directories needed to use CME.
