I just tried a small test case in Visual studio and it worked fine.
Could this be a problem times on cvs servers or something?
---hello.cxx---
int i;
--- depend.cpp----
#include "hello.cxx"
#include "stdio.h"
int main(int argc, char* argv[])
{
printf("Hello World!\n");
return 0;
}
---CMakeLists.txt----
ADD_EXECUTABLE(depend depend.cpp)
Each time I change hello.cxx, depend.cpp recompiles.
