When I run FIND_LIBRARY(MYLIB mylib), the value of MYLIB is the full

Is there a way to get CMake to put /home/bigler/lib/libmylib.a on the
link line instead of breaking it up into path/short name?
No. Why do you need this, it shouldn't be necessary ?
It is necessary on the Mac. GCC on Macs will search *all* the library
paths for a shared version of the library, then search again for a
static version. Since a shared version exists in the default path,
/usr/lib, no amount of -L/mypath will get it to pick the static
version unless I specify the static library explicitly.
There was another thread about this shared library issue a couple of
days ago.
Add this flag to your CMAKE_EXE_LINKER_FLAGS:
-search_paths_first
By default when the -dynamic flag is in effect, the
-lx and
-weak-lx options first search for a file of the
form
`libx.dylib' in each directory in the library search path,
then
a file of the form `libx.a' is searched for in the
library
search paths. This option changes it so that in each
path
`libx.dylib' is searched for then `libx.a' before the next
path
in the library search path is searched.
That will fix the problem on the Mac, I think I am going to make this a
default flag on the Mac since the -l stuff does not work correctly
without it.
