Hello,
I try to create my first FindXXX.cmake and use find_package inside.
My goal is to check that a repository exists: it's always the same because it
come from the ExternalProject_add command.
However, I don't manage to write a first very simple version.
I can't find the path I want.
I would like to check that
/usr/local/bibliotheques/eigen/3.2.4/include/eigen3/Eigen/Core exists.
My file organization is the following:
project/
CMakeLists.txt
build/
modules/
FindEigen.cmake
The CMakeLists.txt contains the following lines:
##
cmake_minimum_required (VERSION 2.6)
project (example CXX)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR}/modules)
find_package(Eigen)
##
The FindEigen.cmake file contains these lines:
##
find_path(EIGEN_INCLUDE_DIR Eigen/Core
HINTS "/usr/local/bibliotheques/eigen/3.2.4/include/eigen3/"
NO_DEFAULT_PATH)
if(EIGEN_FOUND)
message(STATUS "Eigen found (include: ${EIGEN_INCLUDE_DIRS})")
else(EIGEN_FOUND)
message(STATUS "Eigen NOT found (include: ${EIGEN_INCLUDE_DIRS})")
endif(EIGEN_FOUND)
##
>From the "build" directory, I type "cmake .." in a terminal and get:
-- Eigen NOT found (include: )
-- Configuring done
-- Generating done
-- Build files have been written to: project/find_package/build
Could explain me what I am doing wrong?
Thank you very much!
Cédric
