Ich kann mlpack nicht bauen?

Question

Ich arbeite an mlpack-Bibliothek (C++ Machine Learning Library). Ich folgte den Schritten keon hier: building mlpack, aber ich habe den folgenden Fehler in cmd, wenn ich den letzten Schritt erreicht, die mlpack baut:

CMake Warning (dev) at CMakeLists.txt:51 (if): 
Policy CMP0054 is not set: Only interpret if() arguments as variables or 
keywords when unquoted. Run "cmake --help-policy CMP0054" for policy 
details. Use the cmake_policy command to set the policy and suppress this 
warning. 

Quoted variables like "MSVC" will no longer be dereferenced when the policy 
is set to NEW. Since the policy is not set the OLD behavior will be used. 
This warning is for project developers. Use -Wno-dev to suppress it.

Answer 1

Sie haben die Armadillo-Installation verkorkste müssen, um genauer zu sein , Sie haben das Gürteltier nicht angegeben.

Nach this detailliertere Anweisung, Punkt 10:

Geben Sie den Pfad der Bibliotheken, dll und Setup einig Definition, die Details bei here

So finden können, können Sie versuchen, und fügen Sie diese Zeilen zu Ihrem mlpack des CMakeLists.txt:

set(ARMADILLO_LIBRARY "C:/Users/yyyy/Qt/3rdLibs/armadillo/armadillo-5.600.2/vc2015_build/bin/vc2015_x86_amd64/release") set(ARMADILLO_INCLUDE_DIR "C:/Users/yyyy/Qt/3rdLibs/armadillo/armadillo-5.600.2/include")
