Problems with CMake in finding zlib, even if installed

Hello all.
I'm trying to port Avidemux 2.5.6 on OS/2, but got stuck in the CMake
part of the process.
CMake complains that I lack zlib installed. So I simply got the latest
zlib and compiled it on OS/2, then installed the library with "make
install" into /usr/local and /usr/local452 (I have got Paul Smedley's
build environment set on U: with much of the latest software).
After launching again CMake, though, it still complains zlib is
missing. Where am I wrong?
Here follows CMake's messages:
-- Source dir is U:/progetti/avidemux_2.5.6
-- Checking GCC support
-- ********************
-- Check if GCC is x86 32-bit - Yes
-- Check if GCC is MMX2 capable - Yes

Could not find zlib
Call Stack (most recent call first):
cmake/admCheckRequiredLibs.cmake:52 (PRINT_LIBRARY_INFO)

I'm sure I'm missing something...

and probably need to be updated along with the included DEF.
Did you run make check after compiling but before installing? Watch the
beginlibpath so you use the correct z.dll. After installing (you should
only install into /usr/local) have you got the various /usr/local
directories at the beginning of PATH, BEGINLIBPATH, LIBRARY_PATH,
C_INCLUDE_PATH and CPLUS_INCLUDE_PATH?
Also does cmake leave any logs that you can examine?

got an usr/local452 directory, which I believe contains the libraries
built with gcc 4.5.2 and pointed by Paul's build environment using GCC
4.5.2. Fool me, I must check my configuration.
Didn't know, though, that usr/local (or usr/local452, FWIW) must be at
the beginning of the various path environment variables. Will check
ASAP (not tonight, I have other things to do :) ).

of pkg-config and similar tools... Thanks for now!

cmake finds zlib ok here.
\cmake\share\cmake-2.8\Modules\FindZLIB.cmake is what looks for zlib.
What is the anme of your installed *z.a ?
Seems like cmake looks for a lib that matches:
SET(ZLIB_NAMES z zlib zdll zlib1 zlibd zlibd1)
I have a z.a which is a symlink of libz.a - perhaps if you add libz to
the above it will help?
Cheers,
Paul

libtools do everything right then add an extra step that breaks
everything. It's easy to patch but I keep forgetting to make a note of
how. Look at your DLL and import library and DEF and you'll probably
find the DEF has been copied over (or symlinked) the import library or DLL.
Quickest workaround is to just use a static libz. configure
--disable-shared should do it.

All the newer GCCs depend on having gcc 3.3.5 installed and the order of
the above variables is important to bring in things correctly. I'd
assume Paul's build environment is set up correctly.

pkg-config just searches PKG_CONFIG_PATH for its files. eg SET
PKG_CONFIG_PATH=i:/usr/local/lib/pkgconfig;%PKG_CONFIG_PATH% to search
\usr\local first.

Did you run libtoolize to update to an OS/2 fixed libtool? Recent

libtools do everything right then add an extra step that breaks
everything. It's easy to patch but I keep forgetting to make a note of
how. Look at your DLL and import library and DEF and you'll probably
find the DEF has been copied over (or symlinked) the import library or DLL.

PKG_CONFIG_PATH=i:/usr/local/lib/pkgconfig;%PKG_CONFIG_PATH% to search

It solved the problem. Now of course CMake didn't complete for other
problems, but it's for lack of required software. Will try to go
further...

Hi Mentore
Glad that helped - I fixed findzlub.cmake in my local source, so it will
be included in the next cmake/2 release
