Luis,

You need to make sure you are your project into ALL the CMakeLists.txt 
files in the source tree. You should be able to copy files from another 
branch in the tree and edit them for your algorithm. Like at:

pgrouting/CMakeLists.txt   -- search for apsp_johnson (2 places)
pgrouting/src/CMakeLists.txt   -- search for apsp_johnson (1 place)
pgrouting/src/omp/CMakeLists.txt
pgrouting/src/omp/src/CMakeLists.txt
pgrouting/src/omp/sql/CMakeLists.txt
pgrouting/src/omp/doc/CMakeLists.txt  -- this one is an empty file

For you C code, look at:
pgrouting/src/apsp_johnson/src/apsp_johnson.c

and make sure you have similar includes.

Let us know if this helps.
