ConfigVersion.cmake does not work with Windows 10
Hi, Some how i can not use find_package under Windows if there is a ConfigVersion.cmake available. For example, when trying to find GTest following error occurs:
CMake Error at test/CMakeLists.txt:4 (find_package): Could not find a configuration file for package "GTest" that is compatible with requested version "".
The following configuration files were considered but not accepted:
C:/path_to_package/lib/cmake/GTest/GTestConfig.cmake, version: 1.9.0 (64bit)
I am using this line to find the Package:
find_package(GTest REQUIRED CONFIG)
i also tried:
find_package(GTest 1.9.0 REQUIRED CONFIG)
But in this case the versions still does not fit.
Running the same Code under Linux works fine. I am using Windows 10 with cmake 3.13.3 but i also tried cmake 3.12.4.
What am i doing wrong?
GTestConfigVersion.cmake
# This is a basic version file for the Config-mode of find_package().
# It is used by write_basic_package_version_file() as input file for configure_file()
# to create a version-file which can be installed along a config.cmake file.
#
# The created file sets PACKAGE_VERSION_EXACT if the current version string and
# the requested version string are exactly the same and it sets
# PACKAGE_VERSION_COMPATIBLE if the current version is >= requested version.
# The variable CVF_VERSION must be set before calling configure_file().
set(PACKAGE_VERSION "1.9.0")
if(PACKAGE_VERSION VERSION_LESS PACKAGE_FIND_VERSION)
set(PACKAGE_VERSION_COMPATIBLE FALSE)
else()
set(PACKAGE_VERSION_COMPATIBLE TRUE)
if(PACKAGE_FIND_VERSION STREQUAL PACKAGE_VERSION)
set(PACKAGE_VERSION_EXACT TRUE)
endif()
endif()
# if the installed or the using project don't have CMAKE_SIZEOF_VOID_P set, ignore it:
if("${CMAKE_SIZEOF_VOID_P}" STREQUAL "" OR "8" STREQUAL "")
return()
endif()
# check that the installed version has the same 32/64bit-ness as the one which is currently searching:
if(NOT CMAKE_SIZEOF_VOID_P STREQUAL "8")
math(EXPR installedBits "8 * 8")
set(PACKAGE_VERSION "${PACKAGE_VERSION} (${installedBits}bit)")
set(PACKAGE_VERSION_UNSUITABLE TRUE)
endif()
Thanks for your help, Thomas
