Colon after Windows drive letter confuses Make

[Gourmand]

Need release application created in C:\Program Files\app_dir instead of default release dir. I wrote in .pro file:

@CONFIG(release,debug|release): DESTDIR += "$$(ProgramFiles)\app_dir"@

to use system defined variable ProgramFiles. But the Make tells an error: Multiplie target patterns. ProgramFiles opened by qmake in Makefile to line "C:\Program Files\app_dir" and Make confuses with comma after drive letter. It interprets comma as targets delimiter. Probably it is possible force Make get comma as common character using back slash. But if I wrote DESTDIR += "C:\Program Files\program_dir" then qmake replaces all backslashes to "C/:/Program Files/program_dir". Of course this doesn't work too.

Any suggestions how to properly pass comma in path from project file to Make?

Not sure which comma you're referring to. Do you rather mean the colon ":" ?

sorry... colon of course... English is not my native, just mixed words

Which toolchain do you use? MinGW? If yes, which Qt version? There have been some issues regarding spaces in paths in the MinGW makefile generator. Those that I stumbled upon have been fixed in 4.8.1.

The forward slashes should actually work on today's Windows systems. QMake uses them internally, too.

agian - this is NOT about slashes

problem is with colon instead

I would open a bug report against qmake here.
