CMake for non-C project on host without a C compiler - cmake

Question

I'd like to use CMake to generate makefiles for non C project. I don't need a C compiler to build my project. As a matter of fact, I don't have a C compiler installed on the host machine.
My CMakeLists.txt looks like:
cmake_minimum_required (VERSION 2.6)
project (the_thing.html)
LIST(APPEND CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake/Modules/cmake-pandocology")
INCLUDE(pandocology)
add_document(
TARGET the_thing
OUTPUT_FILE the_thing.html
SOURCES the_thing.md
)
When I run cmake on my windows machine:
$ mkdir dict && cd dist
$ cmake .. -G"Unix Makefiles"
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_C_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.
CMake Error at CMakeLists.txt:2 (project):
No CMAKE_CXX_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.
-- Configuring incomplete, errors occurred!
See also ".../dist/CMakeFiles/CMakeOutput.log".
See also ".../dist/CMakeFiles/CMakeError.log".
Those two logfiles give no additional clue. How do I fix that project for it to ignore the absence of a C (and C++) compiler?

Answer 1

You need to explicitly say there are no languages.
project("the_thing.html"
LANGUAGES
NONE
)
That's from one of my projects, but it uses modern CMake (your minimum version is 2.6). The above may work for you, but if not this should do it:
project("the_thing.html" NONE)
