You might use "cmake -E chdir" as a simple test driver:

CMAKE_MINIMUM_REQUIRED(VERSION 2.8 FATAL_ERROR)
PROJECT(CWD C)
ENABLE_TESTING()
FILE(WRITE ${CMAKE_BINARY_DIR}/main.c "
#include<unistd.h>
#include<stdio.h>
int main(void)
{
     char cwd[1000];
     getcwd(cwd,sizeof cwd);
     printf(\"CWD: %s\\n\",cwd);
     return 0;
}
")
ADD_EXECUTABLE(main main.c)
ADD_TEST(NAME maintest
    COMMAND ${CMAKE_COMMAND} -E chdir /var/tmp $<TARGET_FILE:main>)

So, "ctest -V" issues "1: CWD: /var/tmp"; adapt for non-*nices.
