Hi all,
I am getting in trouble with the FindPkgConfig module. Here is a piece
of rather bigger CMakeLists.txt file that doesn't success to find
Doxygen although installed on the machine(ubuntu 10.4, cmake 2.8.3)
# $Id$ #
# ----------------------------------------------------------------------------
# A CMakeLists.txt file to test FindPkgConfig
# ----------------------------------------------------------------------------
set(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS true)
# it MUST go before PROJECT(Jafar) in order to work
if (NOT CMAKE_INSTALL_PREFIX)
set(CMAKE_INSTALL_PREFIX ${CMAKE_BINARY_DIR} CACHE INTERNAL "" FORCE)
endif()
cmake_minimum_required(VERSION 2.6.4 FATAL_ERROR)
project(test CXX C)
include(CheckIncludeFile)
macro(FIND_PACKAGE package_name)
string(TOUPPER "${package_name}" PACKAGE_NAME)
# string(TOUPPER "${package_name}_FOUND" PACKAGE_NAME_FOUND)
pkg_check_modules(${PACKAGE_NAME} ${package_name})
# message(STATUS "finding ${package_name}
${${PACKAGE_NAME_FOUND}}")
endmacro(FIND_PACKAGE package_name)
include(FindPkgConfig)
if(PKG_CONFIG_FOUND)
foreach(package
flann)
string(TOUPPER "${package}" PACKAGE)
string(TOUPPER "HAVE_${package}" HAVE_PACKAGE)
string(TOUPPER "${package}_FOUND" PACKAGE_FOUND)
find_package(${package})
set(${HAVE_PACKAGE} ${${PACKAGE_FOUND}})
if(${PACKAGE_FOUND})
string(TOUPPER "LIBS_MAP_${package}" LIBS_MAP_PACKAGE)
set(${LIBS_MAP_PACKAGE} "${PACKAGE}")
set(LIBS ${LIBS} ${${PACKAGE}_LIBRARIES})
include_directories(${${PACKAGE}_INCLUDE_DIRS})
endif(${PACKAGE_FOUND})
endforeach(package)
else(PKG_CONFIG_FOUND)
message(ERROR " pkgconfig not found you won't be able to build some modules")
endif(PKG_CONFIG_FOUND)
find_package(Doxygen)
==================================================================
It says :
Running CMake to regenerate build system...
-- checking for module 'Doxygen'
-- package 'Doxygen' not found
I get it work by putting find_package(Doxygen) before
include(FindPkgConfig) statement. Can someone explain me this strange
behaviour please ?
Cheers,
