Error while configuring libpng: "zlib not installed"

Question

OS: Win7, using MinGW, sh.exe from MSYS

./configure --prefix=/mingw

with and without prefix ends like this:

checking for zlibVersion in -lz... no
checking for yeszlibVersion in -lz... no
configure: error: zlib not installed

i've installed zlib through cmake, it went smoothly and without errors, so i have all zlib files in my bin, lib and include folders
what can be the problem? how do i fix this?

UPD
looks like it's because i have libzlib.dll and not libz.dll in bin folder, but that's how it installed and i still don't know how to fix it

我最近遇到了这个问题，这是固定的，所以我可以回答这个问题。

如果您正在构建交叉编译器，则使用CPPFLAGS和定义库的主机和路径LDFLAGS。

例子：

CPPFLAGS="-I$PREFIX/include" LDFLAGS="-L$PREFIX/lib" ./configure --prefix=$PREFIX --host=$TARGET

如果您没有构建交叉编译器。然后指定路径（到库和头文件）或安装 zlib devel 包。
