Did you build it using ADD_LIBRARY?
If yes:
PROJECT(HELLO)
ADD_LIBRARY(Hello foo.c)
ADD_EXECUTABLE(HelloBin bar.c)
TARGET_LINK_LIBRARIES(HelloBin Hello)
This is exactly what I have.
ADD_LIBRARY defines the TARGET "Hello" in the above lines. That
should link to the local libHello even if you have another
version in the system.
This is what I thought, too. Unfortunately it doesn't.
This sounds like a bug. Can you send the output of make VERBOSE=1?
Here's the term output (at the end), and a word about the build context:
[...]
I understand cmake smart-orders link directory flags. However, flags
coming from the shell env LDFLAGS don't seem to be taken into account
in this smart sort.
To illustrate the issue, I slightly modified the example code from
http://www.cmake.org/HTML/cmakeExample.tar.gz
The only change is in
cmakeExample.tar.gz:CMakeExample/Hello/CMakeLists.txt
which becomes
# Create a library called "Hello" which includes the source file
"hello.cxx".
# The extension is already found. Any number of sources could be
listed here.
add_library (Hello hello.cxx)
INSTALL(TARGETS Hello
RUNTIME DESTINATION bin
ARCHIVE DESTINATION lib
LIBRARY DESTINATION lib)
As one can see in the attached terminal output, the linker for Demo
looks in /tmp/lib before looking in the build dir:
/usr/bin/c++ -headerpad_max_install_names -fPIC -L/tmp/lib
"CMakeFiles/helloDemo.dir/demo.o"
"CMakeFiles/helloDemo.dir/demo_b.o" -o helloDemo
-L/Volumes/Data/Users/detryr/tmp/CMakeExample/Hello -lHello
As a result, Demo is linked against an obsolete installed version of
Hello, instead of the local fresh one.
Note that /tmp/lib was empty when I ran cmake.
