The Debug and Release configurations of both solutions are set up to build a DLL of the matio library (libmatio.dll) and the matdump tool and assume HDF5 is available in the directory specified by the HDF5_DIR environment variable. It is assumed that the **shared** libraries of HDF5 (and zlib) are available. If the **static** libraries of HDF5 (and zlib) are installed/built the macro `H5_BUILT_AS_STATIC_LIB` needs to be defined (instead of `H5_BUILT_AS_DYNAMIC_LIB`). Furthermore, the Release Lib configuration of the VS2010 solution is set up to build a static LIB of the matio library (libmatio.lib) and assumes that the **static** libraries of HDF5 (and zlib) are installed/built. diff --git a/cmake/conan_provider.cmake b/cmake/conan_provider.cmake new file mode 100644 index 00000000..0d2be004 --- /dev/null +++ b/cmake/conan_provider.cmake @@ -0,0 +1,676 @@ +# The MIT License (MIT) +# +# Copyright (c) 2024 JFrog +# +# Permission is hereby granted, free of charge, to any person obtaining a copy +# of this software and associated documentation files (the "Software"), to deal +# in the Software without restriction, including without limitation the rights +# to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +# copies of the Software, and to permit persons to whom the Software is +# furnished to do so, subject to the following conditions: +# +# The above copyright notice and this permission notice shall be included in all +# copies or substantial portions of the Software. +# +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
