Not able to compile C source files using make. CMake error Cannot find source files but they are there

Question

Im trying to compile the posest C++ library posest : A C/C++ Library for Robust 6DoF Pose Estimation from 3D-2D Correspondences with make. But when run the make I got the following error

make
-- LEVMAR_INCLUDE_DIR = /usr/local/levmar-2.6
-- LEVMAR_BINARY_DIR = /usr/local/levmar-2.6/w32
-- LAPACKBLAS_DIR = /usr/lib
-- demos will be linked against posest;levmar;lapack;blas;f2c
-- Configuring done
CMake Error at CMakeLists.txt:24 (ADD_LIBRARY):
  Cannot find source file:

    mlsl/mlsl.c

  Tried extensions .c .C .c++ .cc .cpp .cxx .m .M .mm .h .hh .h++ .hm .hpp
  .hxx .in .txx

But the source file mlsl.c is already there

Here is the contents of the CMakeList.txt file

Here the Project Directory screenshot.

And the content of the mlsl directory

/home/posest-1.2/mlsl/sobol.h
/home/posest-1.2/mlsl/soboldata.h
/home/posest-1.2/mlsl/sobolseq.c

Im not sure what is the problem. Any help?

Answer 1

I had to download the tar file from the website. It is malformed and won't work.

~/swdev/posest-1.2$ ls -ld mlsl/
drw-r--r-- 2 XXX XXXX 4096 Oct  6  2014 mlsl/
~/swdev/posest-1.2$ chmod u+x mlsl/
~/swdev/posest-1.2$ cmake .

The sources and directories are required to be readable. In this case mlsl has incorrect permissions and CMake cannot read the file. Use the chmod command to fix the permissions on the directory.
