Summary:                    Wrong include path passed to nasm
Description: 
When ASM files are using %include, current CMake configuration for nasm is wrong
and we got "Unable to open include file ...".

That's because nasm seems to need a trailing slash/backslash in path after a -I


Steps to Reproduce: 
Create a project with a .asm file which is including another file (%include
"nasm.inc" for example), use nasm as ASM compiler with
ENABLE_LANGUAGE(ASM_NASM).

Compilation will fail with a "fatal: unable to open include file `nasm.inc'"
error.

Additional Information: 
Output example (without fix):

---
[ 56%] Building ASM_NASM object CMakeFiles/xvidcore.dir/src/bitstream/x86_asm/cb
p_mmx.asm.obj

If I try to launch (notice the backslash after -ID:\Neolinks\xvid\src):

C:\Users\kervala\AppData\Local\nasm\nasm.exe  -ID:\Neolinks\xvid\src\ -f win64
-o CMakeFiles\xvidcore.dir\src\bitstream\x86_asm\cbp_mmx.asm.obj
D:\Neolinks\xvid\src\bitstream\x86_asm\cbp_mmx.asm

It compiles fine even if you replace backslashes by slashes :)

The current ugly fix I'm using to compile my project is (in CMakeLists.txt):

SET(CMAKE_ASM_NASM_FLAGS_INIT "-I${CMAKE_CURRENT_SOURCE_DIR}/src/")

Please could you fix it ?

Thanks a lot
