   Is there an existing issue for this?

   • I have searched the existing issues

   Current behaviour

   when qt@5 is installed along side default brew qt or qt@6 the cmake system will break and deployed application will not build.

   In the build requirements qt@6 is mentioned however the app will not build on this version of qt

   Expected behaviour

   I expected the compiler to use qt@6 as that is what is listed in the build requirement docs.

   Steps to reproduce

   build the app on macos 15.5 with any version of qt greater than qt@5 or when qt@5 is installed alongside any newer version of QT

   Relevant log output

   – Could NOT find Qt5 (missing: Qt5_DIR) CMake Error at /opt/homebrew/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:227 (message): Could NOT find Qt (missing: Qt5_DIR) (Required is at least version “5.11.3”) Call Stack (most recent call first): /opt/homebrew/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:591 (_FPHSA_FAILURE_MESSAGE) cmake/module/FindQt.cmake:59 (find_package_handle_standard_args) CMakeLists.txt:179 (find_package)
