From cd90e28dab3200e48e62a19a9a2187c5d511e01e Mon Sep 17 00:00:00 2001 From: Pierre Ossman Date: Thu, 28 Dec 2023 09:39:08 +0100 Subject: Prevent incorrect cmake usage It's a reoccurring issue that users try to build individual components by pointing cmake at a specific subdirectory, e.g. 'cmake vncviewer'. CMake, unfortunately, has insufficient protection against this so we'll need to add a manual check. This commit only adds it to the most likely places for misuse so we don't have to pollute every CMakeLists.txt. --- tests/CMakeLists.txt | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'tests') diff --git a/tests/CMakeLists.txt b/tests/CMakeLists.txt index 4399dad0..3d0d4390 100644 --- a/tests/CMakeLists.txt +++ b/tests/CMakeLists.txt @@ -1,3 +1,7 @@ +if(CMAKE_SOURCE_DIR STREQUAL CMAKE_CURRENT_SOURCE_DIR) + message(FATAL_ERROR "cmake must be invoked with the top level directory") +endif() + # Benchmarking tools add_subdirectory(perf) -- cgit v1.2.3
