How to use an alternative library outside of linux system

I'm build an opensourced project configured by GNU autoconf. It depends on the glib2.36 and it reports the glib library's version is lower than that. But I don't want to replace my system's glib in the path of "/usr/lib". My idea is to download the glib2.36 and build from scratch and install it to "$HOME/local". Then I want to configure the project using --prefix=$HOME/local.

    $cd ~/tmp/glib-2.36.0$
    $./configure  --prefix=$HOME/local
    $make
    $make install

    $cd ~/tmp/project
    $./configure --prefix=$HOME/local

but it still reports "checking for GLIB - version >= 2.36.0... no" How can I resolve it?

Assuming that your project uses pkg-config and the PKG_CHECK_MODULES macro, you can check where pkg-config looks for .pc files with: pkg-config --variable pc_path pkg-config

You can specify paths for pkg-config to search first by setting the PKG_CONFIG_PATH variable. So, you would invoke configure with something like:

env PKG_CONFIG_PATH="$HOME/local/pkgconfig" ./configure --prefix=$HOME/local

--prefix does't specify where ./configure looks for library. It sets where to install files when you run make install. ./configure --help will show you more options.

If pkg-config is used you cant set GLIB_CFLAGS and GLIB_LIBS env variables to change path for specific package.

But you would check ./configure --help first.
