[CMake] correct DEPENDS behaviour ?

[Alexander Neundorf]

Hiya, 
 
again the same testcase, 
 
CMakeLists.txt: 
ADD_CUSTOM_COMMAND(OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/generated.h 
COMMAND  sh ARGS -c "echo //>generated.h" 
DEPENDS blah.h 
#DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/blah.h 
) 
ADD_EXECUTABLE(hello main.cpp) 
 
and main.cpp: 
 
#include "generated.h" 
#include <stdio.h> 
 
int main() { 
   printf("hello world\n"); 
   return 0; 
} 
 
The issue is: 
 
if I put "DEPENDS ${CMAKE_CURRENT_SOURCE_DIR}/blah.h" in the 
ADD_CUSTOM_COMMAND, the dependency to blah.h is generated as expected in 
build.make: 
 
generated.h: blah.h 
 
if I put only "DEPENDS blah.h" in the custom command, this dependency is 
not generated in build.make. This is an in-source-build and no subdirs or  
anything. Is this the expected behaviour ? 
cmake is current cvs. 
 
Bye 
Alex
