From d040dc18b5e425546d204615866018c374c976e5 Mon Sep 17 00:00:00 2001 From: Iban Cereijo Date: Wed, 14 Jun 2017 15:55:29 +0200 Subject: [PATCH] Problem: CMake evaluation fails with Mingw-w64 Solution: we can use 'CMAKE_SYSTEM_VERSION' instead of '${CMAKE_SYSTEM_VERSION}' for the 'if' clauses. CMake fails to evaluate condition when CMAKE_SYSTEM_VERSION is empty, which can happen with a default installation of Mingw-w64 in Linux. --- CMakeLists.txt | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/CMakeLists.txt b/CMakeLists.txt index 7064582df0..9bbbfc4758 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -183,7 +183,7 @@ include (CheckCXXSymbolExists) check_include_files (ifaddrs.h ZMQ_HAVE_IFADDRS) check_include_files (windows.h ZMQ_HAVE_WINDOWS) -if( ${CMAKE_SYSTEM_NAME} STREQUAL "WindowsStore" AND ${CMAKE_SYSTEM_VERSION} STREQUAL "10.0") +if(CMAKE_SYSTEM_NAME STREQUAL "WindowsStore" AND CMAKE_SYSTEM_VERSION STREQUAL "10.0") SET(ZMQ_HAVE_WINDOWS_UWP ON) ADD_DEFINITIONS(-D_WIN32_WINNT=_WIN32_WINNT_WIN10) endif()
