Bug ID: 19403
Summary: zlib support in windows with MSVC
Product: Build scripts
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: cmake
Assignee: [email protected]

Classification: Unclassified
Why is zlib support disabled for windows/MSVC in CMake?
I got the zlib headers and libraries from GetGnuWin32. I have a code in llvm
that uses zlib algorithm. With the current CMake configuration in LLVM, I
couldn't configure to link zlib.
To detect zlib.h header
-DCMAKE_C_FLAGS="/IC:/GetGnuWin32/gnuwin32/include" -
DCMAKE_CXX_FLAGS="/IC:/GetGnuWin32/gnuwin32/include"
To detect zlib.lib library (dirty hack)
-DHAVE_LIBZ=1 -DCMAKE_EXE_LINKER_FLAGS="C:/GetGnuWin32/gnuwin32/lib/zlib.lib"
-DCMAKE_SHARED_LINKER_FLAGS="C:/GetGnuWin32/gnuwin32/lib/zlib.lib"
The checks to detect zlib library and add it to the linker line are written for
non-windows/MSVC sytems.
I think, blocking the zlib support in windows is a limitation and a bug.
