Description / Steps to reproduce the issue

when I pass compiler versions as environmental variable it doesn't work:

CXX=g++-13 CC=gcc-13 cmake -B build -DBOARD_CONFIG=sim/libcxxtest -GNinja
-- Initializing NuttX                                                                                       
  Select HOST_LINUX=y
  Select HOST_X86_64=y
--   CMake   3.29.5
--   Ninja   1.12.1
--   Board:  sim
--   Config: libcxxtest
--   Appdir: /home/raiden00/git/RTOS/nuttx/apps
-- The C compiler identification is GNU 14.1.1                     <<<<<<<<<<<<<<<<<<<
-- The CXX compiler identification is GNU 14.1.1

should be:

CXX=g++-13 CC=gcc-13 cmake -B build -DBOARD_CONFIG=sim/libcxxtest -GNinja
 Select HOST_LINUX=y                                                                                        
 Select HOST_X86_64=y
-- Initializing NuttX
--   Board:  sim
--   Config: libcxxtest
--   Appdir: /home/raiden00/git/RTOS/nuttx/apps
-- The C compiler identification is GNU 13.3.0               <<<<<<<<<<<<<<<<<<<<<<<<<<<
-- The CXX compiler identification is GNU 13.3.0
-- The ASM compiler identification is GNU
-- Found assembler: /usr/bin/gcc-13

This was broken recently.

@raiden00pl or see if this can work

cmake -B build -GNinja -DBOARD_CONFIG=sim:libcxxtest -DCMAKE_CXX_COMPILER=`which g++-13` -DCMAKE_C_COMPILER=`which gcc-13`
