when all else fail, read the instruction :)

[How can I perform coverage test?]
http://www.cmake.org/Wiki/CTest:FAQ#How_can_I_perform_coverage_test.3F

Currently coverage is only supported on gcc compiler. To perform 
coverage test, make sure that your code is build with debug symbols, 
without optimization, and with special flags. These flags are:

-fprofile-arcs -ftest-coverage

Also make sure to pass these flags to C compiler, CXX compiler, and the 
linker. For example:

  CXXFLAGS="-g -O0 -Wall -W -Wshadow -Wunused-variable 
-Wunused-parameter -Wunused-function -Wunused -Wno-system-headers 
-Wno-deprecated -Woverloaded-virtual -Wwrite-strings -fprofile-arcs 
-ftest-coverage"
  CFLAGS="-g -O0 -Wall -W -fprofile-arcs -ftest-coverage"
  LDFLAGS="-fprofile-arcs -ftest-coverage"


I believe you are missing the proper LDFLAGS, or remove -fprofile-arcs 
-ftest-coverage from the C*FLAGS.
