QtQuick Compiler in CMake

Larvae

Hi,

I put my QML files into a separate qrc/rcc file in a cmake projekt:

qt5_add_binary_resources("res" "qml.qrc" DESTINATION "qml.rcc")

This works fine so far. Now I wanted to precompile them. According to this I only need to change

qt5_add_resources(RESOURCES example.qrc)
add_executable(myapp ${SRC_LIST} ${RESOURCES)

to

find_package(Qt5QuickCompiler)
qtquick_compiler_add_resources(RESOURCES example.qrc)
add_executable(myapp ${SRC_LIST} ${RESOURCES)

So I changed my CMakeLists.txt to

find_package(Qt5QuickCompiler)
qtquick_compiler_add_resources("QML_RESOURCE" "qml.qrc")
qt5_add_binary_resources("res" ${QML_RESOURCE} DESTINATION "qml.rcc")

But now I get
FAILED: qml.rcc cmd.exe /C "cd /D "D:\buildPath" && C:\Qt\5.12.3\msvc2017_64\bin\rcc.exe --binary --name res --output qml.rcc "D:/buildPath/main_qml.cpp" "D:/buildPath/qmlcache_loader.cpp""

There isn't much information about Qt and CMake, so I'm not sure if there is something wrong in my script/Setup or if it's something else. I hope someone can give me some advice.

ps: I'm using QtCreator 4.9.1, Windows 10 and Qt 5.12.3
