[Cmake] Static library linking

[Iker Arizmendi]

I'm trying to have an executable link against the
static Postgres library, but for some reason CMake
insists on generating a link line that refers to
the shared version though I specify otherwise.

The following CMake snippet:

    INCLUDE_DIRECTORIES(${asrdb_SOURCE_DIR}/src)
    ADD_EXECUTABLE(dbadmin dbadmin.cpp dbadmin-args.cpp)
    MESSAGE(STATUS "Postgres Library: ${PGSQL_STATIC_LIB}")
    TARGET_LINK_LIBRARIES(dbadmin asrdb ${PGSQL_STATIC_LIB})

where PGSQL_STATIC_LIB points to "/usr/lib/libpq.a" and
asrdb is my own static library which uses functions exported
by libpq.a. This results in the following output:

Building dependencies. cmake.depends...
/usr/bin/cmake -S/home/iker/network/proj/asrdb/dbadmin 
-O/home/iker/proj/build/asrdb/dbadmin -H/home/iker/network/proj/asrdb 
-B/home/iker/proj/build/asrdb
-- Postgres Library: /usr/lib/libpq.a

...
...

Building object file dbadmin.o...
/usr/bin/g++ -o dbadmin.o  -g -fno-inline -Wall -fmessage-length=0 
-I/home/iker/network/proj/asrdb/dbadmin 
-I/home/iker/network/proj/asrdb/src    -c 
/home/iker/network/proj/asrdb/dbadmin/dbadmin.cpp

Building object file dbadmin-args.o...
/usr/bin/g++ -o dbadmin-args.o  -g -fno-inline -Wall -fmessage-length=0 
-I/home/iker/network/proj/asrdb/dbadmin 
-I/home/iker/network/proj/asrdb/src    -c 
/home/iker/network/proj/asrdb/dbadmin/dbadmin-args.cpp

PROBLEM HERE...

Building executable /home/iker/proj/build/asrdb/dbadmin/dbadmin...
/usr/bin/g++     -g -fno-inline -Wall -fmessage-length=0 -fPIC 
dbadmin.o dbadmin-args.o    -o 
/home/iker/proj/build/asrdb/dbadmin/dbadmin -rdynamic 
-L/home/iker/proj/build/asrdb/src -lasrdb -lpq 
-Wl,-rpath,/home/iker/proj/build/asrdb/src


The link line above refers to "-lpq" instead of "/usr/lib/libpq.a".
Is CMake doing the wrong thing here? Other posts on the mailing
list suggest this is the way to do this.
