Summary0012550: frameworks with spaces breaks cmake
DescriptionTrying to use target_link_libraries with a framework that contains spaces (such as the "Adobe AIR.framework" in the AIR SDK) doesn't work.
Steps To ReproduceFrom an unanswered email on the cmake forums http://www.mail-archive.com/cmake@cmake.org/msg38710.html: [^]


I'm having trouble linking my OS X application to a specific framework using
CMake without explicitly setting linker flags (somewhat defeating the
purpose of using CMake for cross-platform building). Say I have a framework
called "My Framework.framework". CMake successfully finds the framework
when I run:

find_library(MY_LIB \"My\ Framework\")

Then I link to my target with:

target_link_libraries(MyTarget ${MY_LIB})

The resulting linker flag is:

-Framework My Framework

This of course is incorrect and will cause gcc to try to link to "My" and
"Framework separately.

The solution is to write the linker flags myself, as follows:
set(CMAKE_EXE_LINKER_FLAGS -framework\ \"My\ Framework\")

Is there a better way?

BTW, I tried to fix up the name by replacing " " with "\ " i.e.

string(REPLACE " " "\\ " MY_LIB_FIX ${MY_LIB})

Such that MY_LIB_FIX is /Library/Frameworks/My\ Framework.framework. But to
my dismay, CMake interprets this format differently and produces a warning
that says "[the path] is a full-path but not a valid library file name."
 The the resulting linker flag is -l rather than the required -framework.

You shouldn't need any backslashes for the find_library call. This should work:

  find_library(MY_LIB "My Framework")

You can work around this issue by passing the framework like this:

  target_link_libraries(MyTarget "-framework \"My Framework\"")
