compile c++ through shell with jenkins

I'm trying to make a jenkinsfile to compile c++ file through the shell however i'm having the following error:

1.scripts/Linux-Build.sh: 5: cmake: not found

2. scripts/Linux-Build.sh: 5: make: not found

my jenkinsfile:

    pipeline {    
          agent any  
         /*  environment {
           PATH = "${env.PATH}:/usr/bin"    }
        */ stages{
             stage('Build'){
                steps{
                 echo "Building..."
                 echo "PATH is: ${env.PATH}"
                 sh 'chmod +x scripts/Linux-Build.sh'
                 sh 'scripts/Linux-Build.sh'
          }    }    stage('Test'){
            steps{
                sh 'echo "Running..."'
                sh 'chmod +x scripts/Linux-Run.sh'
                sh 'scripts/Linux-Run.sh'
           }    
  }
}
    

Linux-Build.sh: #!/bin/sh

echo "${PATH}"

cmake . make
