[CMake] Linux TARGET_LINK_LIBRARIES bug

[Brandon J. Van Every]

In my toplevel CMakeLists.txt I have:

ADD_SUBDIRECTORY(pcre)
ADD_SUBDIRECTORY(boot)

in pcre/CMakeLists.txt I build

  SET_TARGET_PROPERTIES(libpcre-for-shared PROPERTIES
    COMPILE_FLAGS "${SHARED_FLAGS} -fPIC"
    OUTPUT_NAME pcre-for-shared)

in boot/CMakeLists.txt I link:

  TARGET_LINK_LIBRARIES(chicken-boot libchicken-boot libpcre-for-static)

This works fine under MinGW, and Cygwin.  It also works under MSVC with 
some additional "liblib" code.  Under Linux it dies with

Linking C executable chicken-boot
/usr/lib/gcc-lib/i586-suse-linux/3.3.3/../../../../i586-suse-linux/bin/ld:
cannot find -llibpcre-for-static
collect2: ld returned 1 exit status
make[2]: *** [boot/chicken-boot] Error 1
make[1]: *** [boot/CMakeFiles/chicken-boot.dir/all] Error 2
make: *** [all] Error 2

It seems the target name "libpcre-for-static" is not being propagated 
from the pcre subdirectory, in a way that TARGET_LINK_LIBRARIES will 
pick up.
