OK, CMake does not know what you are doing here. It is treating
LDFLAGS like some linker flag. The idea was something like -64 or
some other linker specific flag for a platform.
Ok.
If you inject directories into the link line, you are sort of out of
luck. Why are you doing it this way?
What other way could I do it?
- There's no official definition of what should be found in LDFLAGS,
but most of the software that use LDFLAGS (in particular autotools)
expect you to put non-standard link directories in there.
You should be using FIND_LIBRARY to find the things you want to link in,
or at least finding the directory with a FIND_FILE, and then using
LINK_DIRECTORIES. LDFLAGS is a bad idea because your users will also
have to set this to get it to work.
- Isn't it the most standard way (in unix) to tell a build system to look
for libraries in non-standard places?
With CMake you should be telling CMake which libraries you want to use.
I suppose we could attempt to parse the LDFLAGS variable. Feel free
to make a feature request, but it won't work for any version of CMake
currently out.
