Extractors are not able to compile

setting option -DBUILD_TOOLS=1 produces errors during cmake/make in Debian 7.2 x64

[SOLVED] adding Build External Ace stopped this error

Not able to compile the map extractors in Debian.

My Build options are:
cmake -DCMAKE_INSTALL_PREFIX=/opt/mZero2 -DDEBUG=1 -DBUILD_TOOLS=1 ..

After running make, this error is produced
