Hi everybody,
I would like to propose a new cmake module for the Armadillo C++ library.
http://arma.sourceforge.net/
This library provides fast linear algebra methods with an interface very
similar to octave code:
colvec x = solve(A,b);
colvec x = inv(trans(A)*A)*trans(A)*b ;
I have attached the FindArmadillo.cmake file to this email.
I propose myself as Module maintainer for Armadillo C++.
My details: Clement Creusot (creu...@cs.york.ac.uk)
Can you tell me if I need to do other steps (in addition to sending this
email) ?
When will the new module file be available to cmake users?
Is there a clean way to provide the FindArmadillo.cmake file for people
installing armadillo that are not likely
to update cmake anytime soon? Is hard-copying the file into
cmakeroot/Modules a good strategy?
Is there an other way to dynamically add a cmake module while installing
a new software?
Best regards,
Clement.
# - Try to find Armadillo include dirs and libraries
# Usage of this module as follows:
#
# == Using Armadillo: ==
#
# find_package( Armadillo RECQUIRED )
# include_directories(${Armadillo_INCLUDE_DIRS})
# add_executable(foo foo.cc)
# target_link_libraries(foo ${Armadillo_LIBRARIES})
#
#=============================================================================
#
# This module sets the following variables:
# Armadillo_FOUND - set to true if the library is found
# Armadillo_INCLUDE_DIRS - list of required include directories
# Armadillo_LIBRARIES - list of libraries to be linked
# Armadillo_VERSION_MAJOR - major version number
# Armadillo_VERSION_MINOR - minor version number
# Armadillo_VERSION_PATCH - patch version number
# Armadillo_VERSION_STRING - version number as a string (ex: "1.0.4")
# Armadillo_VERSION_NAME - name of the version (ex: "Antipodean Antileech")
