Summary0006337: cmake -P crashes on configure_file
DescriptionIt is documented that cmake -P does not have a configuration stage or a cache. However in CMake 2.4.8, if a cmake -P script attempts to execute a configure_file command, the error message says that CMake has not been built correctly. This is worrisome. Run the following script twice with cmake -P to reproduce:

set(input ${CMAKE_SOURCE_DIR}/a.txt)
if(EXISTS ${input})
  set(output ${CMAKE_BINARY_DIR}/b.txt)
  if(EXISTS ${output})
    message("${output} already exists")
  else(EXISTS ${output})
    configure_file(${input} ${output})
  endif(EXISTS ${output})
else(EXISTS ${input})
  file(WRITE ${input} "This is some text")
  message("Created ${input}")
  message("Can't use output of file(WRITE ...) for configure_file")
  message("Re-run script")
endif(EXISTS ${input})

C:\devel\src\cbugs\configure>cmake -P configure_file.cmake
Created C:/devel/src/cbugs/configure/a.txt
Can't use output of file(WRITE ...) for configure_file
Re-run script

C:\devel\src\cbugs\configure>cmake -P configure_file.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be

Can you please check how it behaves with cmake cvs ?

Interesting. Under CMake 2.5-20080213 it dies silently. No messages, either from my message() calls or from error diagnostics. No configure_file output either.
