[CMake] Packaging issues

[Volker Enderlein]

Hi,


I'm facing problems using the packaging with CPACK.

I try to build three different packages, a MSI (via WIX), an IFW, and a 
ZIP package.

According to the documentation I set the following variables in my 
CMakeLists.txt (and a few more which are required):

set(CPACK_WIX_ROOT "C:/Temp/WiX-3.10/binaries")

set(QTIFWDIR "${GLOBAL}/Qt/Tools/QtInstallerFramework/2.0/bin")

set(CPACK_GENERATOR "WIX;IFW;ZIP")

After creating the build dir and running from there

cmake -G "Visual Studio 14 2015 Win64" ..\TestProject

the files CMakeCache.txt, CPackConfig.cmake, CPackSourceConfig.cmake, 
and CPackProperties.cmake are generated.

When running `cpack -C Release` to build all three installers at once, 
the first one (WIX) is built, but the second one (QtIFW) fails with the 
messages

CPack Error: Cannot find QtIFW compiler "binarycreator": likely it is 
not installed, or not in your PATH
CPack Error: Cannot initialize the generator IFW

I inspected the CMakeCache.txt file but found the following entries 
properly defined:

//QtIFW binarycreator command line client
CPACK_IFW_BINARYCREATOR_EXECUTABLE:FILEPATH=N:/Global/Qt/Tools/QtInstallerFramework/2.0/bin/binarycreator.exe

//QtIFW devtool command line client
CPACK_IFW_DEVTOOL_EXECUTABLE:FILEPATH=N:/Global/Qt/Tools/QtInstallerFramework/2.0/bin/devtool.exe

//QtIFW installer executable base
CPACK_IFW_INSTALLERBASE_EXECUTABLE:FILEPATH=N:/Global/Qt/Tools/QtInstallerFramework/2.0/bin/installerbase.exe

//QtIFW repogen command line client
CPACK_IFW_REPOGEN_EXECUTABLE:FILEPATH=N:/Global/Qt/Tools/QtInstallerFramework/2.0/bin/repogen.exe

//Enable to build 7-Zip source packages
CPACK_SOURCE_7Z:BOOL=ON

//Enable to build ZIP source packages
CPACK_SOURCE_ZIP:BOOL=ON

//Path to a program.
CPACK_WIX_CANDLE_EXECUTABLE:FILEPATH=C:/Temp/WiX-3.10/binaries/candle.exe

//Path to a program.
CPACK_WIX_LIGHT_EXECUTABLE:FILEPATH=C:/Temp/WiX-3.10/binaries/light.exe

But when I checked the CPack*Config.cmake files none of the entries 
above are referenced. After running the `cmake -G "Visual Studio 14 2015 
Win64" ..\TestProject` a second time everything is fine; the entries are 
referenced in CPack*Config.cmake files and all three installers can be 
built.

So I really get stuck at this point.


Any ideas what could be the issue and how to avoid it?
