I would put it in Qt4Macros.cmake and document it in FindQt4.cmake.
I would love some other people's input in this work.
I have put some work into it already and can give you the patches I have so
far.
When I started 'using' the functions, they didn't work the way I wanted. So
what I am hoping for was input on what the CMakeLists.txt files should
contain... then maybe we can adjust the functions for installing Qt plugins to
work with that.
Here's a snippet from a CMakeLists.txt file that demonstrates how I wanted to
be able to call it. You'll notice how the functions follow the install()
command style. There is some of passing the same arguments into each command,
but at least the caller doesn't have to formulate a different set of arguments
for each function call. If there is a totally different way to think about
this, I'm open to suggestions.
===========
function(install_prerequisites ....)
install(CODE "
include(BundleUtilities)
....
fixup_bundle(\"${app}\" \"${libs}\" \"${dirs}\")
"
)
endfunction(install_prerequisites)
include(CPack)
# install target
install(TARGETS testqt DESTINATION bin)
# install Qt plugins in a custom location
qt4_install_default_plugins(DESTINATION bin/myplugins)
# install qt.conf file with custom plugin location
qt4_install_qtconf(DESTINATION bin BUNDLE_DESTIATION . CONTENTS Plugins
myplugins)
# install prerequisites (todo, how to pass installed Qt plugins into this
function?)
install_prerequisites(TARGET testqt DESTINATION bin BUNDLE_DESTINATION .
COMPONENT Runtime)
===========
Also, see attached for patch to Qt4Macros.cmake and FindQt4.cmake.
