First I have installed all the dependent packages including atk 2.18.
Then, I have added them to path.

But, when I try to run ./configure, I am getting the following error:
checking for ATK... no configure: error: Package requirements (atk atk-bridge-2.0) were not met: No package 'atk-bridge-2.0' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ATK_CFLAGS and ATK_LIBS to avoid the need to call pkg-config.
atk 2.18 is cleary added in the PKG_CONFIG_PATH and also LD_LIBRARY_PATH.
So, I though atk-bridge-2.0 is separate and found the packag: at-spi2-atk and at-spi2-core. But, no atk-bridge-2.0 is installed.
Please help.
