Hi, I want to use some required Qt component while others are optional. Apparently if you specify REQUIRED in find_package OPTIONAL_COMPONENTS is ignored. Here is a minimal CMakeLists.txt: project(test) cmake_minimum_required(VERSION 3.5)
find_package(Qt4 REQUIRED COMPONENTS QtCore QtGui OPTIONAL_COMPONENTS Invalid) /home/alex/repo/cmake/build/bin/cmake --version cmake version 3.5.20160303-gf37f cmake fails with: CMake Error at /home/alex/repo/cmake/Modules/FindPackageHandleStandardArgs.cmake:148 (message): Could NOT find Qt4 (missing: QT_INVALID_INCLUDE_DIR QT_INVALID_LIBRARY) (found version "4.8.7") Call Stack (most recent call first): /home/alex/repo/cmake/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE) /home/alex/repo/cmake/Modules/FindQt4.cmake:1333 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:4 (find_package) I expected that if required components are missing cmake bails out while continuing when OPTIONAL_COMPONENTS are missing. My current workaround is: find_package(Qt4 OPTIONAL_COMPONENTS Invalid) find_package(Qt4 REQUIRED COMPONENTS QtCore QtGui) But I would rather use a single line. Am I missing something here?
