cmake doesn't correctly run in a Bamboo script

I want to run an inline script that executes cmake command to generate the build files for my c/c++ unit tests. The Bamboo agent runs on a Windows 10 OS. I installed cygwin on the Agent's server to have cmake up and running. If I run cmake directly on prompt, on the Agent's server, everything works fine.
If I run the same command in my Bamboo script I get the following error:

 

I:\bamboo-agent-home\xml-data\build-dir\CIMX-XFU-JOB1>cmake . -Bbuild  
-- CMAKE_BINARY_DIR=/cygdrive/i/bamboo-agent-home/xml-data/build-dir/CIMX-XFU-JOB1/build

    "/usr/bin/gcc.exe"

  is not able to compile a simple test program.

  It fails with the following output:

CMake tries to compile a simple C application in order to test the gcc compiler, but it fails. I tried to compile the same application using gcc and it works. It seems there is a problem between cmake and Bamboo.

In the Bamboo script, I include the path to cygwin(C:\cygwin64\bin) into the environment variable PATH

Any idea on what can cause the issue?

I found out the problem. Bamboo allows to overwrite environmental variables for a specific testing plan. I redefined PATH adding the path to the Cygwin executables, doing so, CMake can access all the libraries and the executables needed. CMake before generating the build files tests that the C compiler works running a small test application. CMake generates a Makefile that builds and executes this test application. For reasons I still don't understand, the Makefile doesn't have visibility of my redefinition of the environment variable PATH, but it reads Bamboo's original version of PATH. In order to solve the problem, I had to change Bamboo's environment variable PATH.
