Following the instructions from http://eigen.tuxfamily.org/index.php?title=How_to_run_the_benchmark_suite using the following commands:
tar -xjf eigen-eigen-1306d75b4a21.tar.bz2
cmake .. -DCMAKE_BUILD_TYPE=Release -DEIGEN_BUILD_BTL=ON -DEIGEN3_INCLUDE_DIR=..
Results in the following error among the other cmake output:
CMake Error at cmake/FindEigen3.cmake:33 (file):
file Internal CMake error when trying to open file:
Call Stack (most recent call first):
And cmake fails without creating bench/btl/Makefile (and likely many other files) required for the next step.
Changing ".." to the absolute path (/tmp/eigen-eigen-1306d75b4a21 in the example) avoids the issue.
